British singer Leona Lewis has been accused of plagiarising her new song Collide from an up-and-coming dance DJ.The Bleeding Love hitmaker debuted the dance track on U.K. radio on Friday (15Jul11), her first single since last year's (10) I Got You. But now Lewis is facing a legal battle - representatives from Ministry of Sound Records insist the record is a rip-off of young producer DJ Avicii's instrumental club track, Penguin. Ministry of Sound executives have reportedly demanded Lewis' label bosses at Simon Cowell's Syco imprint pull the track from radio and prevent it from being released, according to Britain's The Sun. A Ministry of Sound source tells the publication, "Leona Lewis has stolen our record. Collide is identical to Avicii's track. We've been working on this release for a year, then this week we heard Leona's track. Obviously Avicii is pretty upset about this. "A legal letter was sent to Simon Cowell and our lawyers have said they will take the appropriate action over the song. Surely if Leona knew how similar her track is to DJ Avicii's song she wouldn't have decided to press ahead with the release?" But an insider at Syco is adamant there is no legal issue - because the DJ is properly credited on Lewis' track. The source says, "There is zero legal case to answer. Avicii is already credited as a songwriter on Leona's song. It's a case of sour grapes (jealousy) from Ministry Of Sound."
